Figure 11
GISAS pattern of the sample model introduced above in Figs. 2 and 3: spherical nanoparticles (R = 10 nm, δ = 6 × 10−4), forming a hexagonal dense bilayer on top of a substrate (δ = 6 × 10−6), for a highly symmetric lattice orientation ({11} along x). The incident beam has λ = 1 Å, αi = 0.2°. Bragg rods have been indexed manually. The finite horizontal extension of the rods is imposed through a decay function with correlation length 400 nm. The slight breaking of the mirror symmetry in φf is an artifact of our sample model with its rigid two-particle motif. |
